Welcoming Notes: Yello everyone, Soul here with another update to Eros Overlord: Kamen Rider Spyeros.

It's me birthday today...Yay~. I'm a little miffed at myself. I should've had this out much earlier, and should had a different update out like my RWBY story. But no use complaining about. Here's an update. Yay~

Oh yeah, a little PSA: Production IMS, the studio that animated the likes of Date a Live II, Testament of Sister New Devil, Gotta be a Twintail, Hundred, and Hybrid × Heart Magias Academy Ataraxia; has filed for bankruptcy, so any probability of a season 2 of HxH has gone RIP.

On a positive note, thank you all for the many suggestions for Sylvia's replacement in Team Amaterasu. Note that Sylvia will still be around, but she'll be taking on a little sister role, and she won't be anywhere near the harem. I still remember the feeling of wanting to burn my eyeballs out after that…fucking…scene… BLEGH~!

Anywho, enjoy! Oh, and I'll be on Twitch tonight (June 30th, 9PM EST) live-streaming RWBY Volume 5 with facecam. Come join me and my buddies!

Disclaimer: I do not own Naruto, Hybrid × Heart Magias Academy Ataraxia, Kamen Rider, or any other crossover that'll appear.

Special thanks to NorthSouthGorem for beta-reading. Go check out his self-insert High School DxD fic Waking Dreamers, it's awesome.

And WARNING: Unmarked citrus scenes! This is a citrus story due to the nature of the source material.


"In the far future, Earth was attacked by supernatural invaders. They had come from another dimension through portals, using a weaponry that fused science and magic. Despite all of mankind's weapons known and secret to the world, they are practically useless against the invaders. With the lands devastated by the one-sided war, humans built and retreated to giant floating islands called Megafloats. A scientist named Hida Nayuta developed the Heart Hybrid Gear, a weapon effective enough to allow humans to fight back against the invaders.

Enter the Kamen Rider, a hero not bound to the influence of Doctor Nayuta. Armed with the prototype Sypros HHG, he wandered the world, defending the various Megafloats from the invading forces. After years of protecting the world and its inhabitants, he vanished into legend.

Years later, a new Kamen Rider has emerged to continue the legend of Spyros. Stronger, faster, tougher, and more powerful, he faced danger head on; protecting the powerless and smashing his way through the otherworld machines.

No one knew who he was…until now…"


(Megafloat Japan, Monorail to Ataraxia)

Megafloats: giant cities created above the seas. They represent different countries' major cities, which also serves as administrative zones. The largeness of a megafloat represented the national power of that country. Each country is wandering the seas of the world with their respective unique megafloat. For Megafloats that sailed the seas throughout the world, things like territorial waters held no meaning.

Megafloat Japan is made of the Tokyo Float, Osaka Float, and Kyoto Float; roughly one-third the size of the original homeland. All structures, historical and modern, were safety teleported before the island was decimated by the invasion force.

Bullet trains managed to operate between the float for easy transportation. And one was making its way towards the island connected to the Tokyo Float.

"Hey, Tokihiro-san," a female attendant prodded her male co-worker.

"Hm? What is it, Kimi?" Tokihiro replied.

Kimi frowned. "Have you seen Mai? She was supposed to cover my break."

"She went to go serve the first-class coach," Tokihiro replied, jabbing his thumb in the direction of the first-class coaches, "Around fifteen minutes ago…"

"Uuugh, she's probably lazing around again. I'm gonna go find her and let her have it!" Kimi growled, and marched off to the first-class coach.

Tokihiro grinned, "Now this I gotta see. Catfight~"

Both train attendants made for the front of the car. When they arrived at the coach, they saw nothing about empty seats.

"That's right. This coach has been reserved for a special VIP heading to Ataraxia," commented Tokihiro, walking down the aisle, "Must be nice, having the favor of the Principal aka Supreme Commander."

Kimi nodded, looking up and down the aisle, "Our esteemed guest is nowhere to be found. Neither is Mai-"

A loud, rhythmic thumping suddenly became apparent as they proceeded onward. Curious, they moved down the aisle, the sounds growing louder. The two attendants arrived in front of the restroom, where the door was shaking from the thumps, and the grunts and moans were heard through it.

"Oh my…goodness!" Tokihiro breathed, his eyes widening.

"Ah! Aah! Yes! Nnnh~! M-morrrre~!"

'That bitch!' Kimi seethed to herself, "The cafe onboard is about to close! Will you two hurry it up in there?!" she shrieked. She looked jealous, grinding her teeth and balling her hands to fist, that her fellow female co-worker was having a good time.

Inside the restroom, the sounds of flesh slapping flesh resounded in the tiny space. A blond young man was having a bit of fun with a busty girl with orange hair and purple eyes. He held her against the wall, his cock thrusting deep into her hot, wet snatch. The girl was moaning loudly, arms wrapped around his neck and her thighs supported by the stud. His mouth latched onto one of her bouncing breasts, sucking at a perky pink nipple.

"Ah! Oh, okyaku-sama!" Mai cried out, "That tickles- Ahn~!"

The blonde grinned, swirling his tongue around the nub before moving up to kiss her neck, leaving her teat glistening with saliva. His hands moved from her sleek thighs to her bubble butt, fingers sinking into the doughy flesh, and he used his stronger grip to pound her more vigorously. His darkened cockhead kissed her womb over and over, making him groan as each impact made her spasm and tighten even further. He smirked, seeing the ahegao look on Mai's face; her eyes glazed over and her tongue hanging out.

"Wha~, okyaku-sama," wailed Mai, her pussy contracting, "Cumming! I'm about to cum! I'm cumming! Nhaaaaaahn~!"

Outside the room, Tokihiro and Kimi were red in the face, blushing furiously.

"A-wawawawawa~" whined Kimi, her legs shaking.

"Damn. Whoever's giving it to her is a real inspiration," muttered Tokihiro, an awestuck look on his face.

He glanced at Kimi, who was looking down; her face an atomic red. He frowned and looked down, noticing the tent in his pants. Finally feeling it, he quickly covered his erection with his hands and innocently whistled.

"Um, Hiro-san…" Kimi said timidly, her hand on her mouth and pointing at her co-worker's pants, "You um, want to have your lunch break with me?"

Tokihiro's jaw dropped at Kimi's subtle suggestion, just as the door opened.

Mai limped out with a satisfied look on her face. She was wiping distractedly at her face, which was glazed with a white, sticky substance.

"Sorry, Kimi-chan. I was making sure that our guest's trip was...as comfortable as possible," giggled Mai bashfully, nevertheless smiling brightly, "I just…got a little sidetracked."

"Sidetracked? More like on the fast lane to the mile-high club," retorted Tokihiro, snorting.

A young man stepped out of the restroom, zipping up his pants. He was 5'8", had spiky, blond hair, blue eyes and whisker-marks on his cheeks. His attire included an orange and black t-shirt with a flame design, a black headband around his head, blue jeans with a black cross on the left leg and red sneakers.

'Woah, he's handsome! No wonder Mai fell for his charms!' Kimi thought. She blushed when she saw the tent in his pants, and tempted to reach out and touch it 'Is he even human?'

"You know my eyes are up here," the blonde mused to the female attendant, "Unless…you want a turn?"

"Uh no, I'm good!" Kimi squeaked,shaking her head. She grabbed her her co-worker and dragged his away, "Enjoy the rest of your trip!"

The blond chuckled, and waved at them,"Hey buddy! Have fun being a human dildo! Ciao~!"

"Like you're one to talk!"

Chuckling to himself, the young man went back to his seat. "Another day, another conquest. I love being me."

He dug into his bag and pulled out a brochure titled 'Strategic Defense Academy: Ataraxia.'

"But now it's back to my old stomping grounds," he mused, flipping through the pages, "If one can call it a stomping ground. Oh well, I might get to punch Nayuta in the face if Reiri lets me."

His phone buzzed, prompting him wave his hand in the air. At this gesture, holographic screens appeared around him. "Hm? Speak of the devil and she shall mail me…" He scrolled through one of them until he found a new email, and opened it.

'Dear Naruto,

I've finalized the paperwork for your admission to Ataraxia.

Come immediately. Report to HQ at noon tomorrow.

Reiri.'

Naruto's eye twitched a moment before he scoffed, "Office job my ass. As a pervert otaku, her social skills are the worst! She contacts me out of the blue to come to Ataraxia, only to send this? I didn't ask to be to admitted to Ataraxia. She is in for one rude awakening. Hmm, chicken feathers and honey, or sewer water and oompa-loompa color dye? Decisions, decisions…"

'NOW ARRIVING AT ATARAXIA.' An electronic female voice resounded from the train's PA speaker system, 'PLEASE HAVE YOUR ID READY FOR THE BORDER CROSSING.'

The announcement drew Naruto out of his musings, drawing his attention to the outside. The train was now out of the tunnel, giving him a view of the circular island of Ataraxia.

"Man, it really has been 10 years, dattebayo." Naruto commented, putting a hand in his bag, where a technological utility belt rested, "I'm home, Ataraxia…"

'WELCOME TO ATARAXIA.'

Chapter 01: The Eros in Spyros


(Ataraxia)

"Woah. This place really underwent innovation." Naruto whistled, admiring the reflective buildings from the Immigration Center, "I'm surprised they made a residual area too; even more so when they made Ataraxia into a school of all things."

"Uzumaki Naruto, your identity has been confirmed," said the lady in the toll booth, "I trust your trip was enjoyable?"

Naruto smirked. "In more ways than one."

"That's wonderful," chirped the toll lady, smiling. It was unclear whether she caught his double meaning. "I see that you're scheduled to attend the Strategic Defense Academy Ataraxia?"

"It was kind of last minute, but yeah," agreed Naruto, grimacing, before thinking, 'For now…'

"In that case, welcome to Ataraxia! Enjoy your stay!"

The barrier opened, letting Naruto through. He nodded gratefully at the toll lady and winked, making her cheeks go pink.

'If the girls are as cute as her and the one on the train, then I guess this trip won't be too bad,' thought Naruto, pulling a fedora out of his bag and putting it on, grinning 'I wonder if she's wearing the same panties as Mai-san? Heh heh heh…'

In addition to being a notorious prankster, Naruto was also a perverted playboy. The catalyst for his hobby of one-night-stands was the doujinshi his late friend Kizuna stole from an Ataraxia lab tech years ago. When he'd escaped and stayed with Reiri, Kizuna's elder sister, he'd discovered her own stash of porn, and went through them out of curiosity; from JAVs (Japanese Adult Videos), to hentai anime and h-doujinshi. Because of such an early exposure to adult content, puberty hit the blond like a freight train. The weight of what he'd watched and read nearly fried the poor Uzumaki's brain, but lucky Reiri was there for him.

But that was a story for another time. Long story short, it made Naruto into a massive pervert with a healthy libido and quite the master of one-night stands. Naruto always enjoyed the company of the females he slept with, as long as they were cute, beautiful and had large boobs.

He refused to touch underdeveloped girls, however. They simply weren't interesting to him.

'And now I really want to stay,' a smirking Naruto mused, 'Those one-size dress shirts, and the short skirts. The uniforms look really good on these ladies.'

Of course, he made sure to control his facial muscles. He didn't want his smirk to be perverted in nature. He wanted to be known as an infamous prankster, not a shameless pervert that girls would run from. Despite the post-apocalyptic nature of the world, society was still a stick in the mud.

As he admired the many girls hanging around the place, Naruto took in his surroundings. The girls all wore the the same form-fitting white and red academic uniforms. The isle of Ataraxia had the makings of a thriving metropolitan area, with many places that could be found in a shopping district like cafes and restaurants. He was mildly impressed that the constructors had managed to build all of it, on a manmade island no less. The Megafloats were a technological marvel that will take years to be surpassed.

Eventually Naruto arrived at the center of the island, where most of the students were gathered, walking around and mingling. Holoscreens featuring ads floated through the air, but he paid them no mind. The atmosphere was warm and friendly, causing Naruto to be more relaxed than he was before.

"Are you a new transfer student?" a male student who walked by him asked, "Welcome to Ataraxia!" Likewise, a group of female students walked passed him as well, "Nice to meet you."

Smiling, Naruto nodded to the male student and waved lightly to the female students.

"That's Yurishia-sama for you! You can say that again!"

Naruto's ears perked up at the familiar name of 'Yurishia'. He turns towards the source of the voices to find a familiar figure flanked by her two friends.

It was a beautiful, young, Caucasian woman, 5'5" tall, with long blonde hair reaching down to her lower back. She had brilliant blue eyes like his, fair skin, and had a mature aura compared to her age. She also boast a large rack, her bust bouncing and swaying obviously with every step.

'Well well well, if it isn't America's ace, Yurishia Farandole. So, she left the MASTERS group, eh? Didn't see that coming,' thought Naruto, slightly surprised to see her as a student of Ataraxia, 'But damn, her boobs are as big as ever. I think they grew a few inches…'

He watched as Yurishia walked by with her friends, admiring the bounciness of her tits. To him, it was almost hypnotic.

"Hey! Stop right there!"

Naruto was knocked out of his perverted thoughts and looked towards the source of the cry. His eyes widened at other familiar face; a girl who was chasing down a male student.

It was a beautiful young Japanese woman who's 5'1" tall, and has long black hair decorated with red ribbons, that kept her hairstyle into braided twintails. She had blue eyes and long eyelashes well. She wasn't as big as Yurisha, but she wasn't lacking in the boobs department, with a respectable D-cup bust.

"I can't ignore something so lewd~!" she yelled after her quarry.

'Himekawa Hayuru? Understandable, but questionable. I hope she's not beating herself up over that incident a couple years ago,' pondered Naruto, frowning concernedly, 'Still, good to to see her chest swell up some. Hmm?'

The boy who was running away from Hayuru had dropped a magazine. The latter walked over and picked it up to see that it was an adult magazine, evidenced by the big-breasted topless model on the cover.

"And other one for the collection," he drawled cheerfully, slipping the magazine into his bag for later reading.

Just then, his phone rang, indicated by an icon flashing in front of him. Taking a walk, he tapped the blinking icon, producing a holoscreen that had a familiar face on the other end.

"Naruto, did you make it here without incident?" Hida Reiri asked her surrogate little brother without preamble.

Naruto rolled his eyes, but nodded. "More or less. However, any reason you up and blindsided me about my admittance here? Especially while I was on my way here? That's something you never enclosed when you said to get my ass over here discreetly."

Reiri scowled back at him, "That will be explained when you report to the Command Center. I need you and your Heart Hybrid Gear as well. That's all I'll say for now."

"Nice uniform by the way, Reiri-nee. Could you kindly explain to me why you're talking as if you're my Commanding Officer?" he retorted, "I'm a freelancer, remember? Also, if you had a promotion from your abyssal desk job, why didn't you invite me for to celebrate-"

"JUST SHUT THE HELL UP AND GET YOUR ASS TO HQ IMMEDIATELY, UZUMAKI NARUTO!" Reiri suddenly exploded at Naruto, the one holoscreen multiplying and swarming him.

The blond sighed audibly at Reiri's usual short-fused temper. 'She's worse than me, I swear to god dattebayo…'

"I ALWAYS GET WHAT I WANT! AND WHAT I WANT IS THE CORE INSTALLED IN YOU-"

Groaning irritably, he reached out with two fingers and made a downward swiping motion, dismissing the screens and ending the call. He sighed loudly, and noticed the nearby students giving him strange looks. Grumbling, Naruto rolled his eyes and stalked off.

"Nothing to see here, people. Nothing to see at all. Please return to your regularly scheduled… well, whatever you were all doing…" he drawled, before walking out of the area.

He found himself in the forest area. Without break his stride, he took out the porn magazine and began to read it. Without taking this eye off the 'literature', he opened up a holoscreen and speed-dialed Reiri's number.

"NARUTO!" she shrieked the moment her face appeared on screen, "I SWEAR TO GOD IF YOU HANG UP ON ME AGAIN-!"

"If you insist on yelling at me like an aunt on her period, I'm going to transform and Mach 3 my ass out this damn place," he snarled, flipping a page and not even looking at a furious Reiri, "Now, explain why you trapped me into the Ataraxia school system without my consent, or I'm leaving!"

Reiri gritted her teeth, "I couldn't tell you because your line isn't a secure one!"

"My line's always secure," Naruto drawled, "Considering my clientele, it's a necessity. Strike one."

"Are you reading a porn mag?!"

"Of course. The tits are so big in here that I want to stick my dick in them. Strike two!"

"Argh, you little brat!" Reiri shrieked, "Fine! The reason I need you is because the Heart Hybrid Gear Eros installed within you can save the others HHG Pilots! Happy?!"

That stopped Naruto in this tracks.

"You should've started with that," he said quietly.

"I'm sorry, but it's classified. Plus, we learned this just last week!" Reiri snapped, slamming her fist down, "It was found in Nayuta's notes, and it took a while to verify after we decrypted them. I'll explain the rest when you get here, so move your ass!"

Naruto was about to respond, but Reiri hung up.

"Geh, such a troublesome woman. Just get to the point. This isn't an anime," growled the blonde, dismissing the screen again, "But there's a way to save these girls after all… You really should've called me the second you found out."

He grumbled to himself, and pulled out a box of pocky. He stepped out of the forest area, and found himself at the edge of the island, staring out at the ocean. With the sudden breeze, and the bright blue sky in sight, he smiled, feeling at peace. He took a little stroll until he spotted a grassy hill that overlooked the ocean waters.

Making his way over to the hill, Naruto finished off his pocky and lay down on his back on the grassy surface, angled so that he was facing the ocean.

"Doubt I can find a view like this anywhere else on the island," Naruto mused to himself, tilting his fedora down over his face.

Reiri could wait. Naruto was still miffed at her using such shady tactics to get him back to Ataraxia. They weren't even needed, since Naruto would have come running to Reiri whenever she called for him. Especially when he had an itch that needed to be scratched.

With that in mind, Naruto closed his eyes to take a little nap.

"And who are you?" asked a female voice over him.

The blonde grumbled something incoherent before taking his fedora off his face. He sat up, rolled the sides of his neck and shifted to look up at the newcomer. "Hm?"

There was a beautiful young woman staring down at him. She was 5'3" tall, had long, flowing silver hair practically down to her knees, red eyes, fair skin, and large breasts. The only difference between her and the other girls is that she's one exotic beauty.

Not only that, but Naruto immediately saw another girl in her place. A girl with the same silver eye and red eyes, and wearing a pink patient gown...six years ago. The comparison made Naruto's eyes widened, as she recognized the girl.

"Hmm. Do you lack the intelligence required to understand human language?" she questioned, adopting a thinking pose, "I've never met such an organism."

"Well, at least I can understand what manners are," he deadpanned back, getting up and dusting himself up, "Language like that makes me question if you're even a student here."

"Of course I'm a student. What else could I be? Are you suggesting that I'm some kind of weirdo who appropriated a uniform and snuck past the heavy security just to enjoy the scenery here?" she asked with a straight face.

Naruto looked baffled, "A bit touchy, aren't ya missy?"

"Touchy? Whatever could you mean? Why would I bother doing anything like being touchy with the likes of you?" the girl asked, holding out her leg, "I suppose it only makes more sense if you were to get on your knees and beg to be touchy with me. Or you could go a bit further and kiss my feet instead, you inferior creature?"

'What the hell is with this chick?!' wondered Naruto incredulously, his eyebrows shooting up towards his hairline, 'The train's rolling, but its way off the tracks! Condescending and sheltered; yeah, she definitely that girl from before. Considering your choice of wording, it shows me how sheltered you are. Guess that wicked tongue of your hasn't earned you many friends."

"Why would I want friends? They would only slow me down," she stated bluntly, "No doubt you would especially."

"Ouch. Fucking ouch," Naruto mock-winced, "I'm not a fan of that cold personality of yours, but I guess it's better than being a crybaby, amirite?"

"I do not cry, and I'm certainly not a baby!" the girl snapped, folding her arms under her breasts in affront, "I am Chidorigafuchi Aine of Class 2-A. Now, I give you permission to worship me. I'll even forgive you for calling me a crybaby."

"Keh. Six years says different, Aine-chan," said Naruto sagely, turning around and shrugging, "I'm still a bit hurt that you up and rejected me. But that offer is still on the table. Let's me help you make some friends, and cool that icy demeanor of yours. What say you?"

Aine frowned at the blonde, who smirked back. He reached out towards her and held out his hand. He appeared to be offering his support with a friendly smile on his face. As soon as he did that, the motion triggered a memory from a decade ago.

"It's you…" she growled, and pointed dramatically at him, "You're the coward who ran away! Uzumaki Naruto!"

"So I'm a coward for preserving my life? Oh Nayuta, I'm really going to breaking your fucking nose dattebayo," Naruto chuckled, before sighing, "I may be a coward in your mind, but at least I learned more than I would've in that stuffy lab. Considering how condescending you've turned out, I made the right decision."

"As if. Dr. Nayuta taught me the essentials, and they made me strong. I doubt you've learned anything of value in the outside world!" Aine shot back.

Naruto rolled his eyes, "You poor little sheltered brat-"

*UUUUUUUUU~*

A loud electronic wailing suddenly resounded around the island. Red holoscreens flashed up in the area where the general populous was, including Naruto and Aine.

"The air raid siren?!" Aine gasped, "But we're in the middle of the Pacific!"

"Well, there's a familiar sound…" mused Naruto, looking around, "Seems that there's so such thing as Safe Zones anymore. The otherworlders are really vamping up their 'Entrances'."

"You need to run. You're a coward, so you're pretty much useless here," said Aine, unzipping her uniform jacket.

Naruto was about to retort until he saw her drop her jacket. She then unzipped her skirt and let it fall to the ground.

"Are you seriously stripping right now?" questioned an amused Naruto.

"The only one watching is you! I told you to run, you coward."

Naruto ignored the insult. "You know, if you want some privacy, you should've run to one of those nearby trees." he pointed out, gesturing to the forest area, "Besides, there's no way I'm saying no to a free exhibition show that's happening in front of me, crybaby."

"A coward and a lecher. Right now, I'm a poor victim, and you're a perverted Peeping Tom," retorted Aine, unbuttoning her dress shirt.

"The poor victim excuse went out of the window the moment you started stripping on the spot-" snapped Naruto, only to falter as Aine shucked her shirt altogether. "…Wearing your Pilot Suit under your uniform? Heh, A+ for constant vigilante."

Said pilot suit had the appearance of a baby-blue one-piece swimsuit, which exposed most of her cleavage, along with a diamond-shaped hole for her belly button. The suit was held together by a strap over her hefty tits, and a button under her boobs. The suit also included a pair of black fingerless gloves that reached up to her elbows, and black heeled boots that reached up to her thighs.

"So your knowledge starts and ends with women's undergarments? You really are worst." Aine turned away from him, "ZEROS!"

"That's not underwear, you dolt," Naruto replied in mild annoyance. Even so, he stood back and watched as blue glittering lights surged out of the busty girl, her silver hair glowing a soft pink.

The light reformed into armor parts that fitted themselves onto Aine. A vertebral column ran down her back, while a bunch of larger, curved panels latched onto her shoulders and sides. The main cylinder boosters formed around her thighs, and connected themselves with belts around her mid-section. Next, armor parts formed on her limbs with booster attachments for greater mobility. Finally, a headset formed around her temple and ears, with her pink hair turning back to silver.

"The Heart Hybrid Gear: Zeros…" said Naruto, waving his hand to summon more holoscreens, full of charts and graphs on the Gear in question. "Hmm. Well-balanced, stealth and close-combat speciality, and…your Heart Hybrid Count is in the red."

"No, you're wrong on both counts. I do have a weapon, and my Count is adequate." Aine retorted, walking past him, "It seems that my weapon is invisible to idiots. How pitiful."

"Do your ears need to be cleaned out, Aine-chan? I only said Zeros specialized in stealth close-quarters combat. I do see that you have a weapon, but it's inaccessible at the moment." Naruto growled, following after her, "My concern is your Count. I would advise not fighting for long, or hell not at all." Naruto recalled seeing Hayuru and Yurisha earlier.

"Keep your concerns to yourself, you cowardly pervert," Aine shot back, just as a holoscreen appeared next to her with the words 'SOUND ONLY'.

"He is correct, Chidorigafuchi Aine. Your Heart Hybrid Gear Count is below ten percent. The Commander advises you to remain on standby." a feminine voice said.

The holoscreen disappeared as Aine scoffed, "As long as I have a single charge, I will fight."

She stopped and reached down to turn a handle on the ground, then lifted it up. A huge metal case rose up out of the earth, having been cleverly hidden. Inside was a stockpile of rows upon rows of weapons, all much larger than anything that could be efficiently wielded by a normal human.

"Oh? That that's some hardcore preparation." Naruto noted, as Aine hauled out a large anti-material rifle, "Though I should note that-"

"Why don't you keep quiet? I doubt you can contribute anything to my battle strategy. You're a coward after all. Now hurry up and run away, unless you wish to die," Aine rebuffed coolly.

She faced the sea and ran before jumping off the railing. She used her boosters to fly upwards to engage one of the descending Magitech Knights.

"Such a lovely girl," he commented sarcastically, digging into his bag, "Then again, her personality is one to be expected. She was raised by Nayuta, after all. I tried to warn her but…" he sighed, watching as Aine opened fire on the Knight, only for her bullets to bounce off its armor, "The Magitechs are improved over the years. Normal weapons won't work anymore. Not to mention…"

He looked back to see a squad of human-sized Knights marching through the forest. These were a new breed of Magitech soldiers, made to sabotage the opposing side's ground operations. Armed with laser-edged swords and shields with rifles attached to the sides of them, they marched towards the blonde. He rolled his eyes and pulled out the utility belt he'd acquired six years ago.

Through many customizations and repairs over the years, the belt had taken on a slightly different design. Many of the gadgets such as the camera and binoculars, as well as the weapon parts, were still stored on the belt. The phone from before, however, was docked slightly on the right, with a crank likewise jutting off that side of the belt. On the left side, near the middle, were two slots, along with a lever. Finally, the two capsules from before, Heart/Hybrid and Magic/Technology Fullbottles, were permanently installed into the phone; their purpose being to make way for new form changes.

"Category D: Squire. Well then," Naruto mumbled, typing in '3-7-5-7' on the phone. After a click, he closed it and flipped the lever to the left side to unlock it. "WAKE UP! BURNING WAR MACHINE!" "Let's see if you buckets of bolts can make my day more exciting." He placed the belt on his waist, "Dattebayo…"

"HEART HYBRID DRIVER!" the belt announced. A strap shot out and around Naruto, to secure itself to his waist.

The Squires reacted by surging forward as one, ramming their shields and swinging their swords at the blonde, who jumped back, away most of the sword swipes. Leaping up, he braced his feet on one shield and pushed off, propelling himself even further back, vaulting over another Squire that had snuck up on him. Landing, he grabbed it by the arm and Judo-tossed it, slamming it into the ground. Sensing another sneak attack, Naruto pivoted on one foot, leaning away from another swing, and punched the offender away. The Squires opened fire, prompting him to grab a defeated Knight and lift it over his body, using its mass as a shield. The volley hammered his impromptu cover for a few seconds before lessening to allow the Squires time to recharge. In that time, the blond jumped up onto the railing and rebounded off it, leaping over the hail of bullets to deliver a roundhouse to two of the Squires. The Squires were knocked into their benethen and to the ground like bowling pins.

Naruto quickly dug into his pockets and drew out two Fullbottles. He shook them for a few seconds before using his thumbs to twist the caps. Hopping to the side to avoid a deadly energy blast from one of the Knights, he plugged the capsules into the two slots in the Driver.

"FOX!" "RIDER!"

"MASOU MATCH!"

Naruto grabbed the crank and turned it, causing the bottles to glow and a melodic tune to emanate from the belt. Then, a pair of pneumatic tubes spouted from the belt, the essences pouring out of them to form armor pieces that formed into the body of the suit.

"ARE YOU READY?!"

Naruto raised his arm, pointing his finger at the Knights like a gun, "Henshin!" he barked, drawing back his hand and snapping his fingers. At the same time, he pumped the crank down.

He was enveloped in a white light as the suit snapped onto him, completing the transformation. In the place of Naruto was a fully armored individual, with the armor being orange, red, and black in color. The helmet bore a pair of large, orange 'bug eyes' and a set of wings on the sides, styled like fox ears. The body and limbs were covered in a sleek, orange armor, with a pair of red chevrons pointing up the middle. Underneath the armor was a black undersuit for mobility and flexibility.

"FOX! FOX! SPYEROS FOX! YEAH~!"

"Kamen Rider Spyeros," Naruto introduced himself with a mock bow, "The Eros in Spyros. Now, if you all would line up an orderly fashion to meet your demise, that would be absolutely fantastic."

The Knights swarmed at him in response, making his sigh and rub the back of his head.

"Now really… I said," he kicked a Squire into the water, "In an orderly," he leapt forward and punched a Squire into a tree, "Fucking," he tripped a few of them up with a low sweeping kick, "Fashion!" Decking a Squire with an overhead punch that smashed through its helmet and knocked it to the ground.

He grabbed two weapon components, a blade and a triangular handle, from his belt and assembled them. He attached the handle to the blade, with the tip of the triangle aligned to the blade. He grabbed the handle and pressed the trigger on it, causing the blade to grow, tripling in size.

"MASOU SABRE!"

The remaining three Knights back away and fired a barrage of bullets, but Naruto deflected the bullets with his constructed sword. He then gathered the bullets at the trip of his blade and swiped outwards. The bullets impacted the joints of the Knights, freezing them in place. Naruto rushed then, spun on his heel, and beheaded the Knights.

He looked back at Aine, noting that she was holding her own; evidenced by her using her rifle as a melee weapon to destroy the Knights, "Looks like Aine-chan's got this locked down here. I better go check on the students and civilians."

Naruto sped his way through the forest area. On the way, he noted that the ground was rising up, revealing an interception system, from rocket launchers to railguns, that opened fire at the oversized Magitech Knights. Some of the rockets and rail blasts made contract, but they were only half as effective; doing only to push them back and dent their armor.

"The whole island…? This has Reiri-nee written all over it." Naruto commented, snorting, "What are they even firing at?"

He looked to where the interception system was firing upon, and saw a shadow over the clouds. Using his helmet's vision, he saw a towering metallic structure.

"An Otherworld Battleship. I'll deal with you later." Naruto growled.

When he arrived back to the center of the island, he heard a heavy thud behind him. He turn to see a towering Magitech Knight, albeit a different variant. It was round, bulky, and heavily armored, with its horns bearing a resemblance to a hercules beetle.

"Category B: Viking."

Before Naruto could take it down, however- "Blade!" the Viking was suddenly hacked into pieces before exploding right in front of him.

"Gee, that didn't sound familiar at all," Naruto chirped, ignoring a sword being pointed at him, "Long time no see, Neko."

"Why are you here, Kamen Rider Spyeros?" demanded the voice of Himekawa Hayuru.

Naruto turned to look at her with a bored expression on his face under his helmet. He noticed that she was clad in her Heart Hybrid Gear, Neros. It adorned her in red and white armor that's somewhat similar to a samurai in the Edo period.

"Aim that sword somewhere else, and maybe I'll consider answering," Naruto responded sagely, putting his own sword over his shoulder.

Hayuru didn't comply, "As the leader of Ataraxia's Morals Committee, I advise you to answer me, Spyeros."

Naruto responded by knocking her sword away from him with his Masou Sabre, "Since you didn't comply, I'm under no obligation to answer you, Neros. And now is not the time to bicker. See?"

He pointed upward, where a crowd of Category A Knights descended onto their position. Naruto and Hayuru then stood back to back, their swords raised against the Knights that surrounded them.

"This isn't over between us," Hayuru told the Rider.

Naruto groaned, "And what exactly did I do to get you all hot 'n bothered?"

Before Hayuru could answer, a swarm of lasers danced around the surrounding Knights. As soon as it ended, the Knights exploded where they stood.

"Hayuru, be a dear and think for once."

Naruto and Hayuru looked up to see Yurishia Farandole, outfitted in her Heart Hybrid Gear: Cross. Her armor was blue and gold in color, slightly bulky and sleek. She bore a powerful ballistic launcher, attached on her back and supported by a belt around her waist.

"I can't do this alone, you know. If you don't fight we'll all in trouble, so would you mind not slacking off?"

"What was that, Yurishia-san?! You dare accuse a member of the Morals Committee of 'slacking off'?! Take it back this instant!" Hayuru yelled, pointing her sword at Yurishia.

"Oh my, it seems I've touched a nerve," Yurishia giggled. Just then, however, she spotted the armored Rider, "Ah, Spyeros! Long time, no see!" she called out, waving.

"Yo, Yurishia-chan!" Naruto greeted with a little salute, "I see you upgraded Cross. These Knights didn't stand a chance."

"Ah, ever the flatterer~ And I see you met Hayuru."

Naruto shrugged, "Eh, we've known each other before this."

"I see. So you're an item then?"

"Item?! How lewd! Not in the slightest!" Hayuru shrieked, "Get your mind out of the gutter, you nasty girl! We have a more important and noble goal form that to achieve!"

"Sorry for interrupting girls, but can someone tell me that the students and civilians are safe?" Naruto asked loudly, while pulling out a new Fullbottle and shaking it.

"Everyone has been accounted for." Yurishia replied, "All we need to do is mop up the rest of these Magitech Weapons. If we don't move our butts, Ataraxia will be wiped out, and all of Megafloat Japan will be sunk."

"You two go do that then," Naruto suggested while pulling out the Kitsune Fullbottle, "I'm going to deal with their main ship." he said, inserting the new Fullbottle into his Driver.

"RABBIT!" "RIDER!"

"MASOU MATCH!"

After turning the crank a few times and with a, "Henshin!",Naruto pushed it down.

"RABBIT! RABBIT! SPYEROS RABBIT! YEAH~!"

Spyeros' armor changed to a red color scheme with a blue chevrons pointed upwards in the middle. The 'bug eyes' changed from orange to red with antenna sticking out diagonally, and the legs included springs in the shin area.

"What? You meant to take out their mothership?! That's insane!" Hayuru squeaked, waving her arms.

"Wouldn't be the first time I pulled it off." Naruto retorted.

With a wave, Naruto took running starting before jumping onto a tall building. Using the springs on his legs, he jumped the height of a 20 story building. At the same time, boosters sprouted form his back, enabling him to fly towards the direction of the armada in the sky.

As he got closer, she saw Aine. He frowned when noticed her suit's lights were blinking on and off. His HUD in his helmet opened up a screen showing her HHG gauge at three percent.

"Disengage now. I'll take it from here." Naruto called out and sped past her.

"Who?" Aine looked baffled before snapping, "I don't care who you are! Mind your own business!"

Naruto ignored her as he went to work. He jumped onto a Knight and slashed its head off. Before it could explode, he bounded off it and leapt towards another Knight. He rinsed and repeated, destroying almost 30 Knights in under a minute in a streak of light. He backed off, noticing more of the Knights coming out of the main ship.

"Tch." Naruto muttered. He took out a chip, the Spyros Memory, from his phone and clipped it into his Masou Sabre. He then pushed the lever to the right, and pulled to back to the left. Energy, in the form of bolts, traveled towards the chip in the sword.

"READY, GO!" Naruto readied his blade, which glowed a bright red and orange. "SPYEROS CRITICAL SLASH!"

With a roar, Naruto swung his Masou Sabre in a wide, horizontal slash, unleashing a wave of energy that destroyed the incoming Knights. A few Knights managed to flank him, but Naruto shot upwards to avoid their sword slashes. Disabling his boosters, he freefalled towards the Knights and spun around. The momentum gained allowed him to sliced through the Knights multiple times like a hot knife through butter.

After dealing with them, Naruto saw several of the Knights attacking Aine, who was blocking their strikes with her reinforced rifle. Because her Hybrid Count was low, she was unable to defend herself as a Knight struck past her Life Saver shield. Unable to move, she was sent screaming down to the water below.

"Oh, for-!" growled Naruto, flying at the offending Knights.

He deployed the same strategy by slashing and rebounding off them. After destroying the one that attacked Aine, he shot down towards the girl. At the same time, he switched out his Rabbit Fullbottle for a Hawk Fullbottle.

"HAWK!" "RIDER!"

"MASOU MATCH!"

"Henshin!"

"HAWK! HAWK! SPYEROS HAWK! YEAH~!"

Naruto's Spyeros armor turned orange and black. The eyes took on the shape of wings, and a pair . Focusing energy into his wings, they expanded and folded, allowing Naruto to sped towards an Aine; who was unconscious and Zeros Gear deactivated, leaving her in her pilot suit.

Naruto managed to get to her in time, catching her in a princess-carry position. However, he and crashed into some trees before using his wings to right himself in the air. He managed to soar upwards into the air and sped away from the Magitech Weapons. He looked around, saw an empty coliseum, and flew towards it.

He landed and and set Aine down, "Hey Aine-chan-"

Naruto took one look at Aine, and sighed. Aine was still breathing, albeit with painful-sounding breaths. Her suit was almost worn asunder, most of her body bare with her modesty slightly intact. Her nether regions were covered, but her areolas were slightly exposed.

"Good grief, it's like I'm in a h-doujin," Naruto shook his head before prodding at Aine, "Oi Aine, snap out of it. This is no time to take a nap! Geez!" He poked out the air, opening a holoscreen, "Locate the nearest medical faculty!"

Next to the holoscreen another one opened up next to it with a live feed of Reiri, "Naruto, can you hear me?"

"Not now, Reiri-nee. Aine is down. I gotta get her to the medics." said Naruto shortly, lifting Aine up by the arm.

"I'm aware of your situation, now put her down."

"You wanna run that by me again?"

"Shut up! If you want to save Aine, do exactly as I say."

"Fine! What do you need for me to do?"

"First, grope Aine's chest."

"..."

"MEDICAL FACULTY LOCATED."

"Nope. Good talk." Naruto said lightly before dismissing the screens, "What the hell is Reiri-nee thinking?!"

The blonde doesn't mind groping and fondling some boobs. He'll even engage in some sexual harassment every now and then. But when the Otherworlders attack, there's simply no time for sexual activities. People are in danger, and that's when he draws the line.

"NARUTO! WILL YOU STOP THAT?! THIS IS IMPORTANT!" Reiri shrieked after forcing her signal on Naruto.

"You want me to sexually assault a girl while she's unconscious! Even I wouldn't go that far!" Naruto snapped, lifting Aine up, "You better give me a damn good reason to grope the boobs of a girl I just met or so help me-!"

"IT'S TO RECHARGE HER HYBRID COUNT SO SHE WON'T DIE!" Reiri finally exploded.

"THEN WHY DIDN'T YOU SAY SO BEFORE?!" an outraged Naruto roared at her, not missing a beat.

"Commander Hida. Uzumaki Naruto. Please calm yourselves. Allow me to explain." The feminine voice who had informed Aine of her Hybrid Count spoke up. A blank holoscreen flashed up, bearing the words 'SOUND ONLY.' "Uzumaki Naruto, I know this is isn't an ideal situation, but it is necessary for the restoration of an HHG Pilot's Hybrid Count. The Eros Core you inherited from Hida Kizuna is the key, and thus only you can return the Pilots to fighting form."

"Please Naruto. This is an emergency. Aine is under my command, and I alone will take the heat for this just this once. So please, Naruto," begged Reiri, "Work that magic that bedded you so many girls. Give Aine's chest a good rub. Slowly and gently, but with a little force, just like you've done to mine." Naruto sweatdropped under his helmet as Reiri continued, seemingly oblivious to what exactly she was saying. "Remember, don't think, just feel. Feel Aine's body and soul through her boobs. If you can't, she's dead. This is the only way to save her."

Naruto gritted his teeth as an unpleasant memory come to the forefront of his mind.

"D-Dr. Nayuta? No…Doctor…stop! What are you doing?!"

"Someone, stop! Stop it!"

"No! I don't want to die! I don't want to die!"

"Someone, anyone…anyone…!"

"I'm going to…!"

"Nooooooooooooooooooooooooo-!"

"Naruto?" a concerned Reiri asked when he was unresponsive, "Naruto!"

Naruto jumped and shook his head. He was breathing really fast from the memory. He pressed a button on the side of his helmet, causing it to collapse into his suit.

"No way…" he growled, his eyes flashing red, "There's no way…that I'm gonna let Aine-chan, Yurisha-chan, and Hayuru-chan, die like her!" he declared, and glanced at the unconscious Aine. "Sorry, Aine-chan, but bear with this," he murmured, opening up a holoscreen that showed Aine's Hybrid Count.

Gently, he laid Aine down on the ground, cupping her cheek and rubbing it with his thumb. Getting a reaction in the form of a whine and a weak shift from her body, his hand traveled slowly down her neck to her chest. He traced his hands along her shoulders, wrists, chest, as if doing a check up; lightly caressing her chest and abs.

'Her skin is so soft and smooth,' the blonde mused, stroking the exposed, plump flesh of Aine's thighs, 'It's like she's never even seen battle. And…'

He watched Aine's breathing, noticing that she was sweating. Her unconscious, near-naked, defenseless form alone made Naruto hard, his stiffness bulging through the leg of his tight-fitting armor. Her boobs wobbled and jostled with every harsh breath, the strap over her cleavage frayed almost to snapping. Her nipples were also visible thanks to her shredded, swimsuit-like outfit, perking up and stiffening in the open air.

"Heh. If I was a lesser man, I would take you here and now without a second thought. Luckily for you, I'm not that kind of guy. Still," he spread her legs apart, reaching down to stroke her damp, thinly-covered mound, "You're pretty wet and I've barely done anything. Must be having a hell of a wet dream."

His hands steadying Aine's legs, Naruto leaned forward and licked Aine's covered pussy, dragging his tongue slowly up along the fabric. The white-haired girl moaned and squirmed at the action. Naruto held her legs apart to keep her thighs from crushing his head. Not minding the action, since it was expected, he traced his tongue against her folds; using circling and zig-zagging motions.

Naruto then side-eyed his holoscreen, noticing that Aine's Hybrid Count was slowly rising. 'How is this even possible?' he wondered, casually flicking his tongue against her clit, causing her to cry out. Her body started to glow a bright blue.

"Nn, haa...ahhn~" Aine moaned, opening her eyes to see Naruto.

"As expected of you, Naruto. You sure know how to make a girl gush," praised Reiri, nodding. Even over the comms, it was plain that she sounded more than a little breathless.

Naruto's eyes momentarily turned pink, 'The light of her Heart Hybrid Gear…'

"N-Naruto?" asked Aine in a tiny voice, her body shivering from the foreign feeling that made her head feel numb, "What are you-"

"You're cute…" Naruto smiled, kissing her on the cheek, lost in the moment as Aine's face burned, "Now, let's get that Hybrid Count up," He slipped his hands under Aine's suit and firmly grasped her breasts, fingers sinking deep into the supple, pillowy flesh.

Aine let out a cry, as if climaxing. Above her and Naruto, two strands of energy floated out with them. Pink energy flowed out of Naruto, whilst blue energy escaped from Aine. The two energies danced around each other before merging together to flow into Aine. This caused her hair to turn pink momentarily before returning back to its natural silver.

At the same time, familiar images popped up in Naruto's head.

A beautiful lake, snow-covered mountain peaks.

A huge city with tall buildings.

A huge, mechanical clock that covered a whole wall.

And this time, the back of a young girl with pink hair, who turned to look at him with her hair shadowing her eyes.

'Th-That was…' Naruto muttered, holding his head.

"Success! I knew you could do it, Naruto!" Reiri cheered, her holoscreen moving close to HHG Pilots while Naruto snapped out of it, "What you have done with Aine is a Heart Hybrid."

"Heart Hybrid?" Naruto repeated, looking at the holoscreen showing Aine's stats before exclaiming, "Her Hybrid Count is recharged to 75%!"

"Yes," Reiri confirmed as Aine sat up, exclaiming herself, "Heart Hybrid is a fusion of heart, spirit, and more importantly, love. That is the true power of the Heart Hybrid Gear!"

"I can't believe it worked. This is the power I've seen seeking. The power to save them from death," breathed Naruto, clenching his fist, 'With this…' He brought a hand to his chest; to where the fused Core of Eros and Spyros lay, 'No one else has to…die…' An incredulous, almost giddy grin spread across his face…

Suddenly Naruto's senses alerted them to an incoming attack thanks to his empath ability detecting negative emotions from Aine. Flaring his Hawk wings, he quickly shot up into the air. When he was above the trees, he looked down at Aine, who had lashed out with enough force to launch a small shockwave. Her red eyes were narrowed to furious slits.

"You coward! What did you do to me while I was unconscious?!" she seethed, glaring up at him, before looking at her hand and clenched it experimentally, "But…I feel so light." She gazed at Naruto's holoscreen, her brow furrowing in surprised confusion. "My Hybrid Count is up. How? It was almost zero…"

"Seems like you have enough energy to punch my lights out. Can't say I blame you. You're welcome, by the way," snorted Naruto, pressing the side of his neck to re-don his Rider helmet, "If you want more information, speak with your Commander."

"What are you talking about?!" Aine questioned.

Instead of answering, Naruto pulled out a Fullbottle and swapped it with the Hawk.

"ROCKET!" "RIDER!"

"MASOU MATCH!"

"Henshin!"

"ROCKET! ROCKET! SPYEROS ROCKET! YEAH~!"

Naruto was now donned in cyan, white, and black armor. It was a bit bulkier than his previous armors. His gauntlets were the shape of rockets, and his pauldrons resembled the boosters of a rocketship. The eyes took the shape of descending rockets, and the chest had a single white chevron.

"Now if you'll excuse me, I have a Magitech Warship to send to the scrapheap. By the way," he gave her a cheeky salute, "For a bitter crybaby, you tasted pretty sweet dattebayo. Ciao~!"

"Hey, wait!" she yelled after him as he flew away, "Take responsibility, you coward!" Aine demanded, just as Reiri's holoscreen floated towards her.

"Aine, forget about him."

"Commander, what is this?!" Aine demanded, "How did this happen?!"

"I'll explain later. There are Knights above your position," replied Reiri; drawing Aine's attention to said Knights, "Can you fight?"

"Yes! Zeros!"

In a flash of light, Aine was once again donned in her Zeros HHG Armor. Her Pilot Suit was even repaired, as if it was never damaged.

'With this power…!'

She launched herself into air towards the horde of Knights.

"AAAHHHHHHHHHHH!"

With a battle cry, she charged at one of the Knights and punched it. The impact caved in its chest and created a hole, exploding. Not pausing for a nanosecond, Aine zipped through the explosion and proceeded to attack the Knights. Now one hit was all it took to defeat them, with Aine getting faster with each hit. She soon become a streak of light and plowed through the Knights, wiping them out in an instant, leaving a chain of explosions in her wake.

Aine stopped looked back to find that no Knight remained from her assault.

"Wow!"

Aine looked to see Yurisha and Hayuru flying towards her, "That was amazing, Aine! You beat the remaining army!"

"Yurisha. Hayuru." Aine acknowledged as the two stopped in front of her, "The enemy carrier?"

All three HHG Pilots looked up to see the main ship smoking, with fires and explosions breaking out on its outer layer. An orange bolt blasted it way out of the ship, with the ship suddenly turning around and disappearing.

"It's retreating." Hayuru reported, "Yes, but we destroyed most of the enemy Magitech weapons, so let's be content with that."

"But what happened? Aine was like a totally different person just now." Yurisha commented, looking impressed.

"Well, I-" Aine started, looking unsure.

"Hey, get out of the way! Get out of the way!" a voice yelled from above, "Girls, get out of the fucking way dattebayo!"

The trio looked up to see the same orange bolt that shot out of the ship. It looked to be the size of a small meteor that was zooming towards them. They managed to spread out, allowing the meteor to fall to the ground. Upon closer examination, they saw the meteor was actually Spyeros (in his Spyeros Fox Form); kicking a Viking back down to Earth while turning the crank.

"SPYEROS CRITICAL FINISH!"

Naruto kicked the Viking into the middle of the island, destroying the Magitech Weapon in a huge explosion. The force of the explosion knocked Naruto into the air, but he managed to correct himself in the air.

"ALL HOSTILES ELIMINATED." a metallic feminine reported in Naruto's helmet.

"All in a day's work, dattebayo!" Naruto said as he landed. At the same time, Aine, Yurisha, and Hayuru landed behind him; as a camera zoomed in on them.

Meanwhile, at the Ataraxia Command Center, Reiri sighed in relief, "For now, we've made it through the first stage. The mission is far from over, but the key to its success is the Heart Hybrid. The key to retaking the mainland, to retaking the world we lost!"

"That was wonderful. I love seeing you work," Yurisha praised, clasping her hands together.

"Mmf! I'll thank you just this time, you perv." Hayuru mumbled, crossing her arms and looked away from him.

Naruto sighed, slumping his shoulders, "You've such a killjoy, Hayuru-chan. Is the reason you're hostile to me because I mocked your cup size that one time? To be fair, you were rude to me first."

"You have a lot of backbone for a coward," Aine snipped, "It's hard to believe that you're famed Kamen Rider Spyeros."

Naruto was not amused, evidenced by his voice, "Go ahead. Keep calling me something I'm not. I'm going to make everyday the worst days of your life if you keep crossing me, Chidorigafuchi Aine."

"Now now, please calm down." Yurisha chided, getting between them.

Naruto sighed and pulled out his Fullbottles, "DEFORMATION. CIAO~", returning to his civilian form.

'Oh my god! That's Spyeros?! I never knew he was so handsome!' Yurisha squealed in her mind, her hands over her red face, 'Come to mama!'

Hayuru's mouth was agape, 'What? I thought Spyeros was a perverted brute, not a cutie! Why is the world so cruel?'

'What the hell? How could they be smitten with him?! Stay away from him, he's mine!' Aine growled before blinking, 'Wait. Where did that come from?'

Naruto smirked and did a short, charismatic bow, "A pleasure to finally meet you all face to face. I am Uzumaki Naruto, aka Kamen Rider Spyeros. I've been called here to help you girls in the fight against the Otherworld. Rest assured, now that I'm here, you won't have to worry about dying from loss of Hybrid Count."

"Wait," Aine said, looking baffled, "What do you mean by 'dying from loss of Hybrid Count'?"

"If our Count goes to zero, we die?" a surprised Hayuru questioned, her face slowly turning to shock.

Naruto frowned, "Wait, you were never old? That if your Hybrid Count hits zero, you die?"

"N-no." Yurisha responded, shaking her head. She looked at her teammates, and they shook their heads too.

Naruto sighed, and growled under his breath, "If you three lovely ladies will excuse me, I need to go kill someone…"

END OF CHAPTER ONE


(Be the One by PANDORA and Beverly (Kamen Rider Build OP Theme) (subs from TV-Nihon))

-It has been fifteen years since the Outworlders invaded our world, and plunged the lands of Earth into chaos. Our lands have been forced into Megafloats to stay safe from the Outworlders. The users of the HHG defends the remaining human race from harm, and stands against the Outworlders…-

Naruto continues down the path, with holoscreens appearing: Naruto reading a h-doujinshi. Aine standing on the school building roof. Yurisha walking and talking with her friends. Hayuru chasing down a pervert. Sylvia jumping up and down with excitement. Reiri raising her hands and making groping motions.

Be the One! Be the One! Alright!

Naruto, Aine, Yurisha, and Hayuru hopped as one. An alert holoscreen pops up, and Naruto reaches out and grabs his Heart Hybrid Driver.

Ashita no chikyuu wo nagedasenai kara (I won't give up on Earth's future)

Naruto uses the Heart Hybrid Driver to transform into Kamen Rider Spyeros. He snaps his fingers points outward as the rest of Team Amaterasu lands.

Be the lights! Be the lights! Alright!

Spyeros flies through the air and lands a Rider Kick on a Knight. Reiri is at a port at night, looking out into the distance.

Tsuyoku nareru yo Ai wa makenai (I will become strong! Love doesn't lose!)

Nanika wo tasuke sukutte dakishime (Help something, save something, hold something)

Naruto, Aine, Yurisha, Hayuru, and Reiri each picks up a Fullbottle. They then stand in a circular formation and shake the bottles; with the girls boobs bouncing at the motions.

Kokoro ni furete todoku yo tsutaware (Touch my heart and get through, shout it out)

The full might of the Outworlder fleet attacks Ataraxia. Naruto and the girls fly like streaks in the sky, blasting their way through the Magitech Weapons.

Message okuru yo hibiku yo~ (Send the message, it resounds~!)

Naruto reached out and clenched his hand. Aine then grabbed his arm, followed by Yurisha grabbing the other one and putting it between her cleavage. Aine attempts to kiss Naruto, but Hayuru was yelling at them, embarrassment written on her face. Naruto just smirked before looking towards the horizon.

Eros Overlord: Kamen Rider Spyeros


Next time - Chapter 02: Captain Naruto Uzumaki

After a little sibling quarrel, Naruto is made Captain of Amaterasu, Megafloat Japan's Frontline Defense Squad. After a rock start that involves a string of pranks all over Ataraxia, the team is given a mission to go to an uninhabited island to study it and gather resources. Other than miscalculation that results in an ambush, what could possibly go wrong?

-After-chapter notes

Thank you for reading! As for the next update...who knows, but maybe it'll be Shinigami's Devil Huntsmen.

The Heart Hybrid Driver and parts are based off the Build, Ex-Aid, Den-O, and Faiz. Naruto's forms is based off Kamen Rider Build's forms. They're inspired by the fanmade Build Single Forms I found on YouTube.

The harem so far is: Aine Chidorigafuchi, Yurishia Farandole, Hayuru Himekawa, Reiri Hida, Scarlet Fairchild

-These are the following "mysterious girl" candidates to replace Sylvia in Team Amaterasu when the time comes:

Kyoka Kagamiin (Dragons Rioting)

Alisa Ilinichina Amiella (God Eater)

Tifa Lockhart (Final Fantasy VII)

Chifuyu Orimura (Infinite Stratos)

Sofya Obertas (Madan no Ou to Vanadis)

Stella Vermillion (Rakudai Kishi no Cavalry)

Fremy Speeddraw (Rokka no Yuusha)

Kagura (Senran Kagura)

Naraku (Senran Kagura)

Chikage Hizaki (Triage X)

Sayo Hitsugi (Triage X)

Mirei Shikishima (Valkyrie Drive)

Momo Kuzuyu (Valkyrie Drive)

Rinka Kagurazaka (Valkyrie Drive)

Ranka Kagurazaka (Valkyrie Drive)

Remember, only ONE OF THEM will make it through. You have any more suggestions (from an anime or video games), let me know in the review section. There'll be a poll to choose the lucky ladies after chapter 4 of this story. Sylvia will still be around, but only as a little sister figure, and nowhere near the harem.

With that said, peace out, ja ne, and see you in the next update (and/or stream!)
